Milwaukee police said they found the body of Glenn Willis, 62, in his apartment Friday.

Authorities said a 35-year-old woman, a 24-year-old man and a 22-year-old woman are in custody.

Willis was last seen June 14 leaving a downtown law firm where he worked.

He lived in an apartment at Ogden Avenue and Astor Street. Loved ones said this was not the outcome they were hoping for.

“My heart is very heavy, you know?” said friend Arundel Gillespie. “We’ve been looking for him.”

Police said they found the remains after continuing to follow up to see if they could obtain any more leads to Willis’ location. Willis’ wallet and glasses were found two days after he was last seen on June 14.

On Thursday, police found his vehicle across town at 19th and Mitchell streets. Police searched his apartment early in their investigation and said he wasn’t there.

“There are a lot of unanswered questions,” said co-worker Leighann Orozco.

Orozco worked with Willis at the downtown Milwaukee-based Kohn Law Firm. Police said they were not treating the case as a homicide, but Orozco said many things don’t add up.

“We’ll probably have to wait a little while to get the answers that we want,” she said.

Family members said Willis was diabetic.

Police said they were waiting for an autopsy to determine the cause of death.

Investigators said they'll present the case to Milwaukee's district attorney in the upcoming days.
